BOOKING-CHAIR.

To all 'whom 'it may concern:

Be it known that I, JOHN SMITH, a citizen of the United States, residingat Bingham Canyon, in the county of Salt Lake and State of Utah, haveinvented certain new and useful Improvements in Rocking- Chairs, ofwhich the following is a speciti cation, reference being had therein tothe accompanying drawing.

This invention relates to rocking chairs, and has specially in viewcertain novel improvements therein whereby the same may be adjusted forpersons of different sizes, and also whereby it may be used as areclining chair without any danger of overturning.

In connection with t-he foregoing objects of the invention, a novel typeof buffer for the rear ends of the rockers is employed which the flooror other surface on which said rockers are resting, and finally, theinvention contemplates a novel type of track for supporting the chair,in which provision is made for preventing the rockers of the chair beingdisplaced from said track.

In carrying out the objects of the invention generally stated above itwill, ofcourse, be readily understood that the same is susceptible of awide range of structural arrangement, and details, one practical andpreferred embodiment of which is shown in the accompanying drawings,wherein` Figure 1 is a perspective view of the improved chair and thetrack therefor. Fig. 2 is a bottom plan view of the chair. Fig. 3 is afragmentary sectional view showing the adjustable connection between theseat and the seat frame. Fig. 4 is a plan view of the track. Fig. 5 is adetail perspective view of one of the brackets used for adjusting theseat. Fig. 6 is a detail perspective view of the connection between thefront portion of the seat and the frame therefor. Fig. 7 is a detailview of one of the sea-t adjusting brackets. Fig. 8 is a perspectiveview of a supplemental or filler frame which forms a part of theadjustable connection between the seat and its supporting frame. Fig. 9is a transverse sectional view taken on the line A-B, Fig. 4. Fig. 10 isa fragmentary bottom plan view of one corner of the seat showing theconnection between the same and the filler frame. Fig. 11 is aperspective view of one of the slidable members which connect the frontof the seat with its Specification of'Letters Patent.

y su )oi-tino' frame. F i0'. 12 is a detail er- Pl s; :s

spective view of one of the rear ends of the rockers, showing the mannerof applying f buifer thereto.

Referring to said drawings by numerals, the improved chair is providedwith the elongated curved rockers 1 the rear ends of which are mortisedas indicated at 2 for the reception of a buffer pad 3 provided at itsouter end with a downwardly curved pendent rounded portion t whichprojects well below the plane of the bottom edge of the rockers, so thatthe same will be in a position to contact with the surface upon whichsaid rockers are supported before the same have passed their centers,thereby overcoming any danger of the chair overturning, as will bereadily understood.

In the accompanying drawings, the improved bulfer pad is shown ascomposed of rubber, but it will be understood that any other type ofcushion may be employed.

The seat supporting frame is composed of the usual front and rear legs 5and G, which have their upper portions connected by the front and rearbars 7 and S, and the side bars 9. The feet of said legs have a rigidengagement with the rockers 1 at the front ends and at an intermediateportion, which arrangement provides for a long rearward extension ofsaid rockers so that the chair may be used for reclining. A filler framesurrounds the rear and both sides of the upper portion of the seatsupporting frame, said filler frame being composed of side arms 10 andrear connecting member 11. The side arms 10 are provided with a slot 13for the reception of a headed bolt 14 carried by the front portion ofthe seat supporting' frame which permits of said frame having alongitudinal movement relative to said seat supporting frame and also apivotal movement. The rear connecting member 11 is provided withrecesses or slots 15 adjacent to each end thereof which are spanned by akeeper loop 16 which serves to retain staples or equivalent fasteningmeans 17 therein and which serve to retain said member 11 in rigidengagement with the rear end of the seat 18. Said seat may be of thecompound curve shape shown, or any other shape, and at its under side,and adjacent to the forward edge thereof it carries two spaced apartslide strips 19 which are held thereon by means of screws or likefastening means and which have a transverse slot formed through them asindicated at 20. Said strips fit within recesses or notches Q1 formed inthe front member 7 of the seat frame and are limited in their movementrelative to said front member by means of a strap carried by said frontmember and which passes through the slot 20. The under surface of theseat adjacent to its rear edge is provided with two adjusting brackets.said brackets being regularly spaced apart and composed of a singlepiece of material having one portion bent to form a tiange Q8 which hasa rigid, but detachable screw engagement with the said seat, and apendent vertical portion 2l provided with a vertically7 inclined slot 25and an outstanding lateral lug 26.

An adjusting shaft 2T extends through the rear portion of the seatsupporting frame and through the slots 25 in the brackets` one end ofsaid shaft being projected beyond the side of said frame and carrying ahandwheel or handle 28 for operating the same. Said shaft Q7 alsocarries cam Wheels 29 provided with the spiral cam grooves 30 with whichthe lug of each of the seat brackets engage. Said cam wheel is providedwith a hub 31 having a set screw or the like PL passing through it whichengages with the said shaft 2T so that the said hub may be rigidly heldin engagement therewith.

The seat I8 is provided with the usual side arms and a high back 3d.

The improved rocking and reclining chair described in detail in theforegoing description is especially adapted to use in connection with anovel type of rocker tracks or supports shown in detail in Fig. t of theaccompanying drawings. Said tracks are composed of the two rails 35which are held in spaced relation by means of the crossing strips 36,said rails being preferably held at a slightly7 relative inclination toaccord with the usual relative arrangement of rockers. Said rails areeach provided with a flat bearing surface 37 having an upstanding guardflange 39 at their inner longitudinal sides which holds the rockers onsaid itat bearing surface.

From the foregoing description itwill be seen that by means of theengagement between the lugs 26 of the brackets of the seat and thespiral groove 30 of the cam wheels 29, a rotation of the operating oradjusting shaft 27, will raise or lower the rear end of the seat 18 andat the same time project the same either forwardly or rearwardly7 asindicated in Fig. 3, the forward and rearward movement being permittedthrough the described connection between the frontof the seat and itssupporting frame, as is shown in Figs. 3 and 6.

In Fig. 3 of the accompanying drawings the buffer pad is shown as havinga screw engagement 3a with the mortised portion of the rocker. It will,of course, be understood that the same is but one of many ways in whichsaid pad may be attached, the object sought being to obtain a readilydetachable means for holding said pad in rigid engagement with therocker.

Claim A chair of the character described, comprising a seat supportingframe, the front connecting member of which is notched or recessed,rockers for said frame provided with elongated rear extensions, a Iillerframe having a slidable engagement with said seat frame, a seat havingone portion in rigid engagement with said filler frame, slide stripscarried by the other port-ion of said seat7 said slide strips beingprovided with transverse openings and fitting the notches or recesses inthe front connecting member of the seat frame, a strap passing throughsaid transverse opening for limit-ing the sliding movement of saidstrips. and means for adjusting said seat.

In testimony whereof I hereunto attix my signature in presence of twowitnesses.

JOHN SMITH.
